Create an internal facing load balancer with ... - A frontend private IP address - One backend address pool which contains network interfaces for the virtual machines to receive 1521 (Oracle SQL Node Port) network traffic from the load balancer - One load balancing rule fto map port 1521 on the load balancer to ports in the backend address pool - One probe which contains HTTP health probe used to check availability of virtual machines in the backend address pool - Two inbound NAT rules which contain rules that map a public port on the load balancer to a port for a specific virtual machine in the backend address pool - this provides direct VM connectivity for SSH to port 22 and TELNET to port 23

Create two network interfaces in the backend subnet ... - And associate network interfaces to backend pools and NAT rules
